# hitTestWithSegment(from:to:options:)

Searches the node’s child node subtree for objects intersecting a line segment between two specified points.

## Declaration

```swift
func hitTestWithSegment(from pointA: SCNVector3, to pointB: SCNVector3, options: [String : Any]? = nil) -> [SCNHitTestResult]
```

## Parameters

- `pointA`: An endpoint of the line segment to search along, specified in the node’s local coordinate system.
- `pointB`: The other endpoint of the line segment to search along, specified in the node’s local coordinate system.
- `options`: A dictionary of options affecting the search. See Hit Testing Options Keys for acceptable values.

## Return Value

Return Value An array of SCNHitTestResult objects representing search results.

## Discussion

Discussion Hit-testing is the process of finding elements of a scene located along a specified line segment in the scene’s coordinate space (or that of a particular node in the scene). For example, you can use this method to determine whether a projectile launched by a game character will hit its target. To search for the scene element corresponding to a two-dimensional point in the rendered image, use the renderer’s hitTest(_:options:) method instead.
